Mr Green topped the poll in the North-West for the third election in a row, despite having faced two Supreme Court trials over the Tasmanian Compliance Corporation affair during his last term.

"It's a bittersweet victory because we went out aiming to keep three seats and we didn't do that," Mr Green said last night.

Though his personal support slipped from his 2006 high, with 81.7 per cent of the vote counted he was holding just over a quota with 9833 votes.

"To be honest, I thought (Liberal deputy leader) Jeremy Rockliff would top the poll but the support out there for me has been fantastic," he said.

"We ran a big campaign, a grassroots campaign, and as soon as we got out and started doorknocking, I saw that support was still there."

Speaking from the family farm in Sassafras last night, Mr Rockliff said he was satisfied with his personal result.

"I'm a lot more relaxed than I was at 6pm tonight but obviously things are still on a knife edge for us here in Braddon," Mr Rockliff said.

"I think Brett Whiteley and I have demonstrated over the past eight years that we have worked well together for Braddon and I would hope that voters recognise that with three seats."

He was cautiously optimistic that the Liberals would pick up the crucial fifth seat but it could be at least a week before the results are clear.

Adam Brooks, a near certainty to take a seat, would be a welcome addition to the team, Mr Rockliff said.

The final incumbent sure of a return to Parliament last night was Labor's Brenton Best, who attracted 6260 primary votes.
